I am Splitting large files along a Line END OF STATEMENT
and writing new files. I need to name the files with a running number i.e Statement1, Statement2.... Here is what I have:
String[] filenames1 = statements.list(only);//only is filenamefilter
int count;
for (int k = 0; k < filenames1.length; k++) {
try {
FileInputStream fs = new FileInputStream("C:/statements/" + filenames1[k]);
System.out.println(filenames1[k]);
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
count = 0;
FileOutputStream fos = new FileOutputStream("C:/ABC Statements/Statement" + count + ".RPT");
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(fos));
while ((lines = br.readLine()) != null) {
String mine = lines.trim();
if (mine.startsWith("********END OF STATEMENT********")) {
bw.close();
fos.close();
count++;
fos = new FileOutputStream("C:/ABC Statements/Statement" + count + ".RPT");
bw = new BufferedWriter(new OutputStreamWriter(fos));
continue;
}
if (mine.isEmpty()) {
continue;
}
bw.write(lines);
bw.newLine();
bw.flush();
}
fs.close();
br.close();
fos.close();
bw.close();
} catch (Exception e) {
System.out.println("Exception: " + e);
}
}
I am getting only one file with Statement0
Meaning the names are getting overwritten. What Exactly am I doing wrong with count++
I actually got it. Initializing count outside the for loop somehow solved it.
String[] filenames1 = statements.list(only);//only is filenamefilter
int count = 0;
for (int k = 0; k < filenames1.length; k++) {
try {
FileInputStream fs = new FileInputStream("C:/statements/" + filenames1[k]);
System.out.println(filenames1[k]);
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
FileOutputStream fos = new FileOutputStream("C:/ABC Statements/Statement" + count + ".RPT");
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(fos));
while ((lines = br.readLine()) != null) {
String mine = lines.trim();
if (mine.startsWith("********END OF STATEMENT********")) {
bw.close();
fos.close();
count++;
fos = new FileOutputStream("C:/ABC Statements/Statement" + count + ".RPT");
bw = new BufferedWriter(new OutputStreamWriter(fos));
continue;
}
if (mine.isEmpty()) {
continue;
}
bw.write(lines);
bw.newLine();
bw.flush();
}
fs.close();
br.close();
fos.close();
bw.close();
} catch (Exception e) {
System.out.println("Exception: " + e);
}
}
